Merge #13743: refactor: Replace boost::bind with std::bind

cb53b825c2 scripted-diff: Replace boost::bind with std::bind (Chun Kuan Lee)
2196c51821 refactor: Use boost::scoped_connection in signal/slot, also prefer range-based loop instead of std::transform (Chun Kuan Lee)

Pull request description:

  Replace boost::bind with std::bind

  - In `src/rpc/server.cpp`, replace `std::transform` with simple loop.
  - In `src/validation.cpp`, store the `boost::signals2::connection` object and use it to disconnect.
  - In `src/validationinterface.cpp`, use 2 map to store the `boost::signals2::scoped_connection` object.
